Practical Examples

Example 1 Small Driveway

A 20' × 10' driveway with 4" depth:

Volume = (20 × 10 × 4/12) ÷ 27 = 2.47 cubic yards

Weight = 2.47 × 1.4 = 3.46 tons

Example 2 Garden Path

A 30' × 3' path with 2" depth:

Volume = (30 × 3 × 2/12) ÷ 27 = 0.56 cubic yards

Weight = 0.56 × 1.4 = 0.78 tons
